BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application tiled May 1, 1907. Serial No. 371.326.

To all u'lzmn it muy conrcrn:

lie it known that l, Iunar Donnscn, a citizen ol' the l'nited States ol' merica, and residing at 'Nyack` in the count)r ol Rockland and State ol New York, have invented certain new and usefulImprovements in liot tlc- (`losures. ol' which the following is a specitication, such as will enable those skilled in the art to which it appertains to make and use the same.

lhis invent ion relates to closuredevices l'or bottles, jars, pitchers and other vessels t'or holding liquids and the object thereol' is to provide a gravity closure which automatically closes said vessel when in normal position and which opens and permits liquidsto pass from said vessel when the latter is inclined; a still further object being to provide such a. device which is readily attachahle to and removable lrom bottles or other vessels ol a stock size as lor instance milk, cream, whisky and similar bottles and also to produce such a device which is simple in construction and operation, is readily taken apart l'orcleansing, cannot rcadilyget outof order and is very inexpensive.

My invention is t'ully described in the following specitication` olwhich the accompanying drawings t'orm a part, in which lthe several parts are Idesignated by the same reference characters in each ol' the views,

Figure l is a. vertical section taken through a milk or cream bottle provided with one form ol embodiment ol my invention; Fig. 2 isa side view thereof but showing the bottle in position for pouring liquid therefrom; Fig. Si is a view similar to Fig. but showingr a moditi cation thereof; Fig. 4 isa plan view of Fig. l, and Fig. 5 is a section through theattachment taken on the line 5ur olFig. l but showingthebottle in l'ull lines. Y

ln the drawings forming a part ol this application` l have shown a milk or cream bottle u. provided with the usuat contracted neck'u'2 and bead u externally ot' the top thereol', and, in the form shown in Figs. 1, 2, 4 and I provide a plug b composed ot' a metal-tube b' and a. cork, wood, or paper tube bf, and the top ol the metal tube b'2 is bent outwardly so as to rest upon the top ol' the bottles and this rim bt is provided with two vertical lugs bi each of which is provided with central holes or openings bl and inclined slots b7 in communication therewith and it will be observed that the slots b7 are o lesser diameter than the holes bn and the reason for which will he hereinafter explained.

' Journaled in the holes b is a wire or shaft c which is bent downwardly on each side of the lugs b5 and provided with weights c2 and the shaft c is llattened between the downwardly bent portions so as to slide through the slots b1 when the shaft c is in the necessary position but the shal't will not be removable from the lugs b5 when'in any other position although the size of the holes b permit ready rotation thereof Firnily secured to the flattened portion c3 of the shaft c is a tongue d of the cover d2 and, in practice, the cover Ji and the plate or rim bf are provided with registering ridges c to insure a substantially air-tight closure and by means ol' the permanent connection oi the cover d2 and shalt c it will he seen that when the said shaft is rotated in its hearings the cover is moved correspondingly and if the bottle abe inclined in the proper direction lthc weights clmaintain the cover d2 in a horizontal positionaway trom the neck u, and the liquid is free to pass out` ol' the bottle and when the bottle is returned to its upright position the cover (P is immediately closed. i

In Fig. 3 ol the dran ings l have shown a modification et' the torni described in that I employ 'a metal band f externally of the bottle a beneath the head a3 and this band fis preferably made detachable by means ol' any desired connection of its ends'as -indicated at f l and is provided with two vertical lugs f i in all respects similar to the lugs b5 but in this form ot construction the cover rests directly upon the bottle neck and is secured to the shalt c by means of a tongue h2 and the operation ot this form is similar in all respects to that already described.

ll' desired, the lugs bi,.or equivalents thereof, may be formed directly upon and integral with the bottle a in which event the cover h and shalt c together with the weights (flare all that is necessary to make the desired closure and the said cover, with its gravity operating devices, may be readily adapted to milk and syrup pitchers or vessels et any kind or class which it is desired to cover to prevent flies, dirt. or other foreign matter entering thereinto and suitable catches may be provided to secure the cover in a closed position for shipment and, when so used a cork, rubber or'paper anti-leaking ring may be employed between the bottle and the cover and various other changes in and modifications ol the forms ot construction shown and described maybe made without. departing trom the spirit of my invention or sacrificing its advantages.

llaving fully described my invention, what I claim as new and desire to secure by Letters Patent, is1

1. A device ol` the class described. comprising al vessel. a cover thcrclor. lugs provided with slots mounted on said vessel, a shalt secured to said cover and rotatable in said slots. said shat't bein;Y tlattencd at its bearing points t0 permit the insertion thereof into said slots and said slots being terminated in enlarged recesses,

L. A dcvicc'ol' tlieclass described, comprising a vessel, a cover tlnircfor, lugs mounted on said vessel and provided \\'itlrslots terminatingr in enlarged recesses, a shaft in said slots and secured to said cover, said shaftheing tlattencd to permit 'its insertion into saidl slots, and weights on said shat't. below the axis thereof.

3. A device olI theclass described, comprising a vessel, a tubular plug in the neck thereof, lugs on said plug, a sliat't rotatable iirsaid lugs, a` cover secured t0 said shaft and weights en said slial't below the axis thereof.

4. A device of tht-class described, comprisnga vessel, a cover therefor, a shaft secured 'to said cover, lugs mount! ed on said vessel, said lugs serving as bearings for said shaft said ings heing reessed and said shaft being angulnrly formed to permit the insertion into und preventing.,r the reniovnl of said shaft from said lugs when in any other tlnln one predetermined position, and means for maintaining said shaft and cover' in a horizontal position .when the vessel is moved out of vertical position.

A device of the class described, comprising a vessel, a cover therefor, a shaft secured to said cover, lugs mounted on said vessel and serving as bearings for said shaft,

1() said ings being recessed and said shaft angular-1y formed,

I have signed my name in presence of the subscribing wit- 15 nesses this 29th day of April 1907.
